Abstract
Abstract The ground wheels of a wheeled suitcase are provided with a mount and a socket is fixed to the suitcase to permit the wheels to be readily secured and removed. The socket provided on the suitcase is of minimal thickness and formed so as to obviate snagging with adjacent articles while the suitcase is being transported in the normal manner without wheels.
